Composition of Carlina acanthifolia Root Essential Oil

Chemistry of Natural Compounds, 2005
The root of Carlina acanthifolia All. (Asteraceae) contained 1.0% of essential oil (expressed in g per 100 g of dried plant material). Using GC and GC/MS, nine components were identified (100% of total oil). The structure of benzyl 2-furylacetylene (carlina oxide), which is the principal component of the oil (91.5%), was spectrometrically identified.

Essential oil composition of Santolina etrusca from Italy

Chemistry of Natural Compounds, 2007
The essential oil composition of aerial parts of Santolina etrusca Marchi & D’Amato from Italy was analyzed by GC and GC/MS. Twenty-nine compounds of oil were identified representing 97.1% of the oil. The most abundant compounds were viridiflorol (17.9%), terpinen-4-ol (14.4%), myrcene (11.8%), β-pinene (9.9%), and cis-muurola-4(14),5-diene (9.9%).

Essential Oil Composition of Cilantro

Journal of Agricultural and Food Chemistry, 1996
Leaf oil was isolated from two commercial samples of cilantro (Coriandrum sativum L.) and from growth-chamber-grown plants at five different stages of growth. The oils were analyzed by GC/MS. They were found to be composed mainly of C10−C16 aldehydes. (E)-2-Alkenals predominated.

Chemical composition ofPourouma guianensis Aublet essential oils

Flavour and Fragrance Journal, 1999
The essential oils from leaves, stem barks and pistillate flowers of Pourouma guianensis Aublet (Moraceae) were isolated by hydrodistillation and the volatile constituents were determined by HRGC and HRGC–MS. Methyl salicylate was the major compound identified in all oils studied and was present in yields of 20.8% (leaves), 31.2% (stem bark) and 62.2% (
